Hi, Arthur. One thing I’d suggest thinking about here is the role that unconscious bias plays in the hiring process. It’s not necessarily just about how attractive one looks. See this definition from UCSF:
Unconscious biases are social stereotypes about certain groups of people that individuals form outside their own conscious awareness. Everyone holds unconscious beliefs about various social and identity groups, and these biases stem from one’s tendency to organize social worlds by categorizing.
Many companies are spending real time and effort to reduce the effects of unconscious bias on their hiring efforts. This can include removing photos and even names from resumes, in attempt to circumvent the effects of unconscious bias.
For this reason, I’d suggest not to include a photo on your resume, especially if you feel you might be particularly subject to the effects of unconscious bias.
To see what kinds of implicit biases you might have, check out this test from Project Implicit.
